T on whom it may concern.-

Be it known that I, ALEXANDER J. 11001), a citizen of the UnitedStates,residing at M usooda, in the county of Grant and State ofWisoonsin, have invented certain new and useful Improvements in Tintingand Delivery Attachments for Printing-Presses; and I do declare thefollowing to be afull, clear, and exact description of the invention,such as will enable others skilled inthe art to which it appertains tomake and use the same.

I This invention relates to a tinting and-delivery attachment forjob-printing presses.

The object of the invention is to provide simple and effective automaticmeans for tinting or coloring the sheets of paper or other materiallying on the platen prior to printing and for delivering the tinted andprinted sheets to a suitable receptacle.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of aprinting-press embodying my invention, showing the relative positions ofthe parts when the printingblock. is making an impression. Fig. 2 is asimilar View showing the relative positions of the parts when thegripper engages a printed sheet between the form and platen. and 4. aretop plan views ofthe parts as arranged in Figs. 1 and 2. ing toward therear of the press. Fig. 6 is a detail perspective view illustrating themam nor in which the printed sheets are fed into the chute. Figs. 7 to12, inclusive, are detail views of the various parts of the attachment.

Referring now more particularly to the drawings, the numeral 1represents the bed or frame of a job-printing press of knownconstruction; 2, the platen thereof; 3, the ro' tating inking-plate; 4.,the roller-carrying arms; 5, the crank-disk, and 6 the crank-rod forcommunicating motion from the disk to said roller-carrying arms. 4

Fixed to the rear of one of the arms 4 by meansof suitable clamps 7 is asupporting bracket or standard 8, which has a limited back-and-forthadjustment and which is pro- Figs. 3!

Fig. is a view1ookor standard 8 may be adjusted to regulate theimpression of the color printing or tinting block in the mannerhereinafter described.

The laterally-projecting arm 9 supports an upright arm 11, which has alateral foot 12. This foot 12 and the arm 9 are formed with two sets ofapertures 13 and 14 for the passage of a. pivot-bolt 15 and aclamping-bolt 16, the aperture 13in the foot being in the nature of aslot to allow the arm 11 to turn upon the bolt 15, so that theprinting-block, hereinafter described, may be adjusted in one directionto bring the face thereof into perfect parallelism with the platen 2. Asecond bracket or standard 17 is pivoted at its lower end to the rear ofthe bed or frame 1, as indicated at 18, and has an elbow-arm 19, thevertical branch of which is in advance of the arm 9 over the rotaryinking-plate 3. The two arms 11 and 19 carry pins or rollers 20 21,which fit and slide within a longitudinal slot 22, formed in' anoscillatory link 23. This link carries the printing or stamping block24:, which tints or colors the sheets to be printed, the said blockbeing adjustably secured thereto by means of a threaded stem or shank 25and a clamping-nut 26, which shank is suitably fixed to the block andextends through the slot 22. The nut 26 clamps the block against thelink, so that by loosenin g the nut the block may not only be ad justedlengthwise of the link, but also turned on its own axis to bring theprinting-face thereof when the block is swung downward into accurateparallel relation with the platen 2. The block 24 may carry or embody astamp or cut or type-matter of any preferred kind the subject whereof isto be transferred to the sheet of paperon the platen prior to theprinting thereof in the usual. way, so that a tinted surface or coloreddesigns or matter of any desired kind contrasting in color with thematter to be afterward printed in the usual way may be transferred tothe paper as it is laid upon the platen while the latter is momentarilyat rest. By this means two-color work may be quickly and convenientlyturned out without the necessity of running the sheets a second timethrough the press, as is customary, for a second impression.

The operation of the parts of the apparatus thus far described is asfollows: As the platen 2 moves toward and from the chase or form carriedby the bed 1 and the roller-carrying arms 4 rocktherewith the standard 8follows the arc of travel of said arms and oscillates the link 23,thereby causing the block 24 to oscillate with said link, whereby whenthe platen has been retracted and is momentarily at rest and theinkingrollers are moving downwardly over the surface of the form thestandards 8 and 17 will swing downwardly and bring the printing-face ofthe block downward to come in contact with the sheet of paper resting onthe platen, in the manner shown in Fig. 2. When the platen movesforwardly,the parts are restored to their original positions, asillustrated in Fig. 1. It will be seen that as the standard 17 is fixed,while the standard 8 swings with the arms 4,

the action of said standard 8 in swinging downwardly causes the link 23to turn completely over and to swing on the pin 21 as a fulcrum, bymeans of which the block 24 is given a half-revolution and itsprinting-face is reversed from the position shown in Fig. 1 to thatshown in Fig. 2 to make an impression on the sheet resting on the platen2 prior to the printing of the sheet in the regular manner. When theplaten moves forwardly, the link is thrown back to its original positionand turns the block 24 to again throw the printing-face thereof upward.As the block.

' oscillates its printing-face is inked by one or morerollers27,mountedinayieldingorspring frame 28, supported bya thirdstandard or bracket 29, the rollers being pressed by said frame againstthe printing-surface of the block to insure the proper supply of ink tosaid surface. By the adjustable connection of the arm 11 with the arm'9of the bracket 8 and of the block 24 with the link 23 the said ,block ismade adjustable in two planes at right angles to each other, so that itmay be regulated to a nicety to produce a perfect contact between itsprinting-surface and the sheet to be printed lying on the platen 2.

The bracket or standard 29 is mounted,together with a bearing-block 30,on one or more suitable supports 31, attached to the rear of the bed orframe 1 of the press, and has a forwardly-curved arm 32, terminating atits free end in aslotted plate 33. Adjustably connected to this plate bymeans of one or more bolts 34, slidably fitted in said slot, is abracket-arm 35, carrying a bracket-plate 36, to which is secured a chute37, from which a conductor 38 leads laterally to a suitable receptacle,(notshown,) which may be located off to one side of the machine and isdesigned to receive the printed sheets from the delivery-gripper. Thechute and conductor may be sustained and braced by a rod or bracket 39,extending from the supports 31, and may j moves away from the bed.

be made of any suitable material and construction to suit the purpose.The bracketplate 36 is formed with a T-shaped slot 40, the main portionof which is vertically disposed and the cross portion horizontallydisposed, which slot forms the entrance to the chute 37 for the depositof the printed sheets therein.

The printed sheets are delivered to the chute through the medium of thefollowingdescribed mechanism: Journaled in the hear ing 30 is arock-shaft 41, to one end of which is fixed a crank-arm 42 and to theother end a swinging delivery-arm 43. The crank-arm 42 is jointed to ashort arm 44 on the standard 8 by a connecting-rod 45, while the freeend of the swinging arm 43 is provided with a slotted bracket-plate 44,carrying an adjustable gripper 45. This gripper 45 consists of two jaws46 47, united bya pivot pin or bolt 48, the jaw 46 being movable withrelation to the jaw 47 and normally held closed by a spring 48 The jaw47 is fixed with relation to the jaw 46, being provided with an arm orextension 49, adjustably secured to the slotted bracket-plate 44 by nuts50. The movable jaw 46 carries a trip-lug 51, which is adapted to beengaged by contactpieces 52 53, arranged, respectively, upon the pressadjacent to the platen 2 and upon the chute 37 or its bracket-plate 36to open said movable jaw to engage and release the printed sheets. Afixed part of the press-frame may, however, be utilized to perform thefunction of the contact 52.

The operation of the delivery device is as follows: The crank-arm 42 isso disposed at an angle to the shaft 41 and arm 43 that when thestandard 8 and printing-block 24 swing in one direction the said arm 43will swing in the reverse direction, so that the block 24 reaches thelimit of its downward movement just previous to the time when the platen2 moves toward the bed 1, while the swinging arm 43 reaches the limit ofits downward movementat or just prior to the time whenthe platen Hencewhen the printing-block moves toward the platen the delivery-arm 43-moves, away therefrom, and

vice versa. The operation of the printingl block 24 will be readilyunderstood from the foregoing description. When said block is retractedby the upward movement of the rollercarrying arms 4 and the bracket orstandard 8, attached thereto, the said standard 8 draws upon the rod 45,causing the crank-arm 42 to rock the shaft 41 in a forward direction,thereby causing the swinging arm 43 to be projected forwardly anddownwardly at the time when the platen 2, having forced the sheet ofpaper resting thereon against the type-form on the bed 1, is about tomove away from said bed. As the arm 43 nears the limit of its downwardmovement the trip-lug 51 comes into engagement with the contact-piece52, whereupon the movable jaw 46 of the gripper 45 is opened and allowedto grip between it and the fixed jaw 47 the upper projecting edge oftheprinted sheet 54. As the platen continues to move away from thebed 1 andthe roller-carrying arms 4 swing downwardly again, together with thestandard or bracket 8 and cooperating parts of the tinting or coloringdevices, the crank-arm 4.2 is moved in the reverse direction to thatpreviously described and the arm 43 swung upwardly, while at the sametime the printing-block 24 is moved downwardly to make an impressionupon the new sheet of paper just placed upon the platen 2. As the arm 43nears the limit of its upward movement the gripper 4.5 passes upwardthrough the vertical main portion of the T-shaped slot 40 in thebracket-plate 36 and draws the printed sheet upwardly through the crossportion of-said slot, as shown in Fig. 6, whereby the printed sheet isbrought into the chute 27 and when the trip-lug 51 comes into engagementwith the contact-piece 53 is released and drops down into said chute andthence passes through the spout or conductor 38 to a suitable receptacleat one side of the machine, whereby the operations of tinting -orinitially printing the sheets one color andremoving and delivering themto a suitable receptacle after the second impression has been made fromthe pressform are alternately and automatically performed, thusincreasing the capacity of the press and obviating the necessity ofrunning the sheets to be printed two or more times through the presswhen the printing is to be done intwo or more colors.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, and adanduseful and labor-saving in printing all kinds of work in two or morecolors.
